(a) General rule.--A health care provider or another person may not be subject to criminal or civil liability, discipline for unprofessional conduct or administrative sanctions and may not be found to have committed an act of unprofessional conduct as a result of any of the following:

(1) Causing or participating in the initiating, continuing, withholding or withdrawal of life-sustaining treatment or cardiopulmonary resuscitation from a patient or principal, if the health care provider believes in good faith that he has followed the patient's or principal's wishes as expressed in a living will, order or revocation made under this chapter.

(2) Complying with a direction or decision of an individual who the health care provider believes in good faith has authority to act as a principal's health care agent or health care representative so long as the direction or decision is not clearly contrary to the terms of an advance health care directive that has been delivered to the provider.

(3) Refusing to comply with a direction or decision of an individual based on a good faith belief that the individual lacks authority to act as a principal's health care agent or health care representative or is not acting in accordance with section 5456(c) (relating to authority of health care agent) or 5461(c) (relating to decisions by health care representative).

(4) Complying with an advance health care directive under the assumption that it was valid when made and the health care provider believes in good faith that it has not been amended or revoked.

(5) Disclosing health care information to another person based upon a good faith belief that the disclosure is authorized, permitted or required by this chapter.

(6) Refusing to comply with a direction or decision of an individual based on a good faith belief that compliance with the direction or decision would be unethical or, to a reasonable degree of medical certainty, would result in medical care having no medical basis in addressing any medical need or condition of the individual, provided that the health care provider complies in good faith with sections 5424 (relating to compliance) and 5462(c) (relating to duties of attending physician and health care provider).

(b) Same effect as if dealing with principal.--Any health care provider and other person acting under subsection (a) is protected and released to the same extent as if dealing directly with a competent principal.

(c) Health care agent.--No health care agent acting according to the terms of a health care power of attorney shall be subject to civil or criminal liability for acting in good faith for a principal or failing in good faith to act for a principal.

(d) Health care representative.--No health care representative who in good faith acts or fails in good faith to act for the principal shall be subject to civil or criminal liability for the action or failure to act.
